IIIIVIPROV'IEilillI'Nll'.I IN BASIN-TRAP.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.'

Be it known that L'HUGH H. CRAIGIE, of the city and State ot' New York, have invented and made a new and useful Improvement in Traps for Stationary Basins; and I do hereby declare the following to be a full, clear, and'exact description of the said invention, reference being had to the annexed draw ing, making part of this specitication, wherein- Figure 1 is a vertical section of said trap, as attachedto a basin, and

Figure 2 is a plan of the said trap.

.Similar marks of reference denote the same parts.

This invention is for the purpose of preventing the escape ot .noxious fumes ti'om the sewer-pipe ot' stationary basins.

Some of the stationary basins that are now made, are formed with a short tubular horn or socket at the bottom of the'basin, formed of porcelain or earthenware, in one piece with the rest of the basin.

Diliicnlty arises in connect-ing to this tube the pipe that leads to the sewer.

My improvement is designed with special reference to connecting the sewer-pipe to this character of a basin, and at the same time preventing smell passing ont of the sewer-pipe. I

My invention consists in a trap, with a couplingeonneetion for the sewer-pipe, in combination with a clamping-segment and socket, for the porcelain escape-tube ot' basins, whereby said-trap can be securely attached to said basin with great facility.

In thedrawing* a represents a portion of the lower part of a sta-` tionary basin.

b, the porcelain tube for the escapewater,y and fitted to receive tbc plug c, in any usualv manner. u

(l is the trap, formed with the coupling-screw e, for the sewer-pipe,'the dam f, to prevent smell passing from the sewer-pipe, and the socket g, at the upper end, for setting up around thejtube b.

At one' side of the socket g is a movable section, h, acted upon by ay clamping screw, i, that passes through a projecting arm,l.f.

Putty is to be applied around the tube 0, and then the trap-socket g placed over the same, and the section h firmly pressed against the side of b by ,the screw 1'-, to clamp the parts and hold the socket and trap firmlyto the basin. t

The inward ange 3 sustains the put-ty used for the packine. l A

The trapscrew l allows the workman to smooth the putt-y that may project inwardly between l) and g, and if the trap becomes obstructed, said screw allows of its being cleaned.

What I claim, and desire to secure by Letters Patent, is

The trap d., with, the coupling c and socket f/,in combination with the segment l: and screw i, as and for the purposes set forth.

In witness whereof, I have hereunto set my signature, this 27th day of `March, A. D. 1869.
